Andrew Balbirnie's defiant half century wasn't enough to prevent Ireland Wolves from a comprehensive 8-wicket loss to Bangladesh A in the fourth one-day match in Cox's Bazar.
The Irish skipper top scored with 52 as the visitors were skittled for a disappointing 103. Balbirnie struck three fours and cleared the ropes once in his 90-ball stay.
Balbirnie and Shane Getkate added 48 for the 7th wicket after the Irish had slumped to 54 for 6 after winning the toss and batting first.
However the last four wickets fell for just one run, with Getkate's 23 the only other double figure contribution.
Peter Chase (1-32) and George Dockrell (1-23) claimed a wicket apiece but the hosts raced to victory with 8 wickets and 27 overs to spare - skipper Nazimul Hossain hitting 7 boundaries in his unbeaten 41.
The teams meet again tomorrow in a T20 fixture (5am BST), before the tour concludes with the fifth and final one day match on Thursday.
